Many heads are better then one, right?
Is there a place where we can discuss the analysis of certain cryptographic schemes in detail? In particular, I'm actually writing a cryptoanalysis of https://arxiv.org/abs/1804.06862, but in my humble opinion this should be public and open for discussion.
I'm not a fan of writing a paper on that topic, and then putting it on the arXiv or wherever, because that is too slow and it's better to discuss these things "on the fly".
However, it's important to have certain standards; for example, on Reddit, whose discussions are spammed with a lot of noise from people who lack a proper background in mathematics.
